ASoC: sprd: Add Spreadtrum audio DMA platfrom driver The Spreadtrum DMA engine uses the link-list mode to support audio playback or capture, thus this patch adds audio DMA platform support for CPU DAI to trigger DMA link-list transfer.

ASoC: sprd: Add Spreadtrum audio compress offload support We use 2-stage DMA mode to support Spreadtrum audio compress offload, which means we use one DMA source channel to transfer data from IRAM buffer to the DSP fifo to do decoding/encoding, once IRAM buffer is empty by transferring done, another DMA destination channel will be triggered automatically to start to transfer data from DDR buffer to the IRAM buffer. This can reduce the AP subsystem wakeup times to save power.

Say Y or M if you want to add support for codecs attached to
the Spreadtrum SoCs' Audio interfaces.
ASoC: sprd: Add Spreadtrum multi-channel data transfer support On Spreadtrum platform, the audio subsystem will use the multi-channel data transfer controller to transfer sound stream between audio subsystem and other AP/CP subsystem. It can support 10 DAC channel and 10 ADC channel, and each channel has 512 bytes depth data fifo. Moreover each channel can be used DMA mode or interrupt mode to transfer data.

Say y here to enable multi-channel data transfer support. It
is used for sound stream transmission between audio subsystem
and other AP/CP subsystem.
